What was the capital of the Aztec Empire, located on an island in Lake Texcoco?

Tenochtitlan was the capital of the Aztec Empire and is recognized as one of the most remarkable cities of its time. Founded in 1325, it was situated on an island in Lake Texcoco in what is now Mexico City. The city's location was strategically significant, as it offered natural defenses and access to fresh water and resources. The Aztecs engineered an extensive system of causeways and canals that facilitated transportation and trade, showcasing their advanced urban planning.

The other cities mentioned are important in their own right, but they are not related to the Aztec Empire. Teotihuacan, for instance, was a major city in Mesoamerica before the rise of the Aztecs and is noted for its impressive pyramids. Cuzco was the capital of the Inca Empire, located in present-day Peru, while Machu Picchu is a famous Incan site high in the Andes mountains, known for its well-preserved ruins. This distinction underscores Tenochtitlan's unique status and importance within the context of Aztec civilization.
